2003 Explorer Issues
I am having trouble with my 2003 Ford Explorer XLT Sport. It idles very rough, at times upon starting it will almost stall, then catch. There are no codes, no check engines, no service engine, NOTHING. There are times it will run rough and other times when it purrs like a kitten. When I put the AC on, it runs even worse. Can someone help me, please.

Sounds like you have an issue with the Idle Air Control (IAC) servo or a vacuum leak/misfire. The 2003 with the V8 has the "throttle by wire" system, I'm not sure about the 2003 with V6. If you have throttle by wire, you probably do not have a separate IAC, and then the issue is probably a vacuum leak or misfire.
